Bug report: bots report bad hashes after /backport

[Aleksey Shipilev]

Hi folks,

It seems bots are confused about the repository states. Is this something known?

I did `/backport jdk21u-dev` here:
 
https://github.com/openjdk/jdk/commit/eb9e754b3a439cc3ce36c2c9393bc8b250343844#commitcomment-136598429

Yet the bots say the commit hash is unknown:
   https://github.com/openjdk/jdk21u-dev/pull/151

Thanks,
-Aleksey
